Why does the code below exceeds the loop's condition?

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int num = 1;
while(num < 6)
{
num+=2;
Console.Write(num);
}
}
}
}

output: 3 5 7

Answer 1

Because you are writing after increment inside the loop body.

So when num = 5

while num < 6 true

num += 2 now num becomes 7

Console.Write(num); // prints 7

while num < 6 false, loop ends.
